Best Oil for 5.9 Cummins [Oil Type & Capacity]
Oil Type and Capacity for 5.9 Cummins
As you probably know, the 5.9 Cummins engine is a force to be reckoned with. In the right hands, the truck can be extremely powerful and challenging to handle because of its sheer power. But there are some things to keep in mind when you’re dealing with one. One of those things is oil changes and what type of oil is best for your engine. 5.9 Cummins engines can be found in Dodge, Ford and GM models. The engine is known to have a lifespan of more than 500,000 miles if it’s properly maintained and serviced.
Consensus between Cummins experts is that 5W-40 and 15W-40 are the best oils for operating temperatures above 50 deg F. That being said, the engine must be designed or retrofitted to accept these oils due to the lower pour point (10 deg F @ 5W-40, and -18 deg F @ 15W-40). As such most new engines are now built with this oil in mind. If you’re running a stock engine or if your vehicle needs synthetic oil due to pressure, consider using 5/50 or 10/30 as it will lubricate better in cold weather.

Factor to Consider Before Buying Oil for 5.9 Cummins
Choosing the right oil for your 5.9 Cummins is a very important step to take. Picking the wrong one may result in engine failure and other serious problems.
There are many factors you should consider before choosing your oil, in this article we’ll talk about the most important ones.
Oil Viscosity
The viscosity of an oil refers to how thick or thin the oil is. Thinner oils are better for colder climates and thicker oils are better for warmer climates. This is because viscosity helps to determine how much pressure the oil can handle before it begins to break down. If you want to use an oil that has a low viscosity, you need to make sure that it meets the engine specifications for this type of oil.
Ash Content
Ash content refers to how much ash is left behind after the combustion process takes place inside of your engine. The more ash left behind, the less efficient your engine will run, which means less horsepower and torque from your vehicle.
Additives
Some oils will have additives in them that can have a positive or negative effect on your engine. These additives can include things such as stabilizers, detergents, and others. You should always make sure that the additives are certified by a reputable organization before using them in your vehicle.
Oil Type
Another factor to consider when purchasing 5.9 cummins oil is the type of oil that you want to use in your vehicle. There are two different types of oils that can be used in a diesel engine—conventional and synthetic. Conventional oil is cheaper than synthetic, but does not last as long and does not provide as much protection for your engine as synthetic does. If you want to use synthetic, there are two subtypes—synthetic blend and full synthetic. Synthetic blends offer more protection than conventional oil, but less than full synthetic, while full synthetic offers the most protection available on the market today.
Accurate fitment
You need to make sure that you get the right fitment with your specific engine model. This is why it’s important to check the manufacturer’s specifications when making your purchase. You should also check what kind of environment your vehicle operates in, and whether or not it has been modified for racing or other extreme applications.
Micron size
A micron is a unit of measurement and it is used in measuring the efficiency of the oil filter. The lower the micron number, the smaller the particles it can capture. This means that an oil filter with a lower micron rating is more efficient than one with a higher micron rating when it comes to capturing more dirt and contaminants. The micron size of your oil filter is an important factor to consider. With too large a micron size, some dirt particles might slip through and cause damage to your engine over time.
Dirt control
The level of dirt control is determined by the number of pleats on an oil filter and its diameter. Oil filters with more pleats are able to trap more dirt than those with fewer pleats.
Frequently asked questions
How Often Should You Change The Oil In A 5.9 Cummins?
You should change the oil in your 5.9 Cummins on a regular basis to ensure the engine always has clean, fresh oil flowing through it. How often you change it depends on several factors, but generally speaking, change the oil every 6,000 miles.
Do I Need To Add Oil Additives?
No, using oil additives in your 5.9 Cummins is unnecessary and could cause serious damage to your engine. Additives are designed for use in gasoline engines, not diesel engines. The two types of engines are very different, and additives designed for one type of engine can cause major problems with another type of engine – specifically, diesel additives can create buildup in a gasoline engine, while gasoline additives can cause serious damage to a diesel engine.
How much oil does a 5.9 24 valve Cummins take?
The exact amount of oil needed will depend on whether you’re doing an oil change or a complete overhaul of the system, at which point the engine will be completely drained and will require more oil than usual. Generally speaking, the 5.9 Cummins has a capacity of 12 quarts. On the other hand, a 5.9 Cummins with 24 valves has an oil capacity of 11 quarts and it takes 1 quart in the oil filter.
